SETTING PEARLS ON FINGER-RINGS, 800.

SPECIFICATION forming part of Letters Patent No. 253,667, dated February 14, 1882.

Application filed December 14, 1881.

To all whom it may concern:

Be it known that I, JULIUS BERGFELS, a resident of N ewark,in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Setting Pearls on Rings and other Jewelry; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The object of this invention is to secure a more substantial, durable, neat,and otherwise more desirable setting for pearls and other gems; and it consists in the arrangements and combinations of parts, substantially as will be hereinafter set forth, shown, and embodied in the claims.

Referring to the accompanying drawings,in which similar letters of reference indicate like parts in each of the several figures, Figure 1 is a sectional view of a piece of jewelry, showing pearls therein partially placed in their settings, illustrating the process of fastening the stone therein. Fig. 2 is a side elevation of a fin ger-rin g embodying my improvements; Fig. 3, a shirt-stud in section, illustrating the stone finally disposed; and Figs. 4, 5, and 6 are detail views more clearly illustrating the device, all of which will be fully explained hereinafter.

In carrying out my invention I form upon or secure to the body I) of the piece of jewelry to which the gem is to be applied a shank, a, made preferably tubular in form and of thin sheet metal. This said shank may be split, as shown in Fig. 5, if it be so desired, to facilitate the hereinafter-described operation. I then form in the pearl or gem c a cavity, 01, which islarger at the bottom than at the mouth, as shown, and of a depth about equal to the length of the shank a. I then place a metallic globule, g, which may be an ordinary leaden (No model.)

shot or any wedge-like piece especially prepared for the purpose, upon the end of said shank, pass them together up into the cavity in the gem, and finally by force cause the globule or wedge to pass into the end of the shank, causing the same to spread, as illustrated by Figs. 3 and 6, to fill the cavity, and thus to securely unite the parts, as will be clearly understood. By this arrangement the gem is held with great firmness-indeed it cannot be sep- .same figure, which engages with a corresponding ridge on the seat.

Having thus described my invention, what I claim, and wish to secure by Letters Patent,

- '1. The combination,injewelry, with thebody b, of the gem having the cavity (1 therein, the hollow shank, and wedge, all arranged and operating substantially as and for the purposes set forth and shown.

2. The combination, in jewelry, of the shank carried by the body 1), adapted to be spread, the stone having a cavity therein enlarged at its bottom, and the wedge, all arranged and operating substantially as and for the purposes herein set forth and shown.

In testimony that I claim the foregoing I have hereunto set my hand this 8th day of December, 1881.

JULIUS BERGFELS'.
